NOKTH    AMKKICAN    HYMENOPTKRA.  175* 

Mouograph  Of  the  MUTILLID^C  of  North  America. 


BY   CHAKLEH    A.    BLAKE. 

TIk'  airuiiiulation  of  nuich  new  material,  in  this  interestinji'  family, 
from  all  part.-*  of  the  country  has  siigjre.sted  a  revi.sion  of  tlic  "Sy- 
nopsis" published  in  the  "  Tran.sactions"  in  1871,  which,  althoiiifh 
tolerably  complete  at  that  time,  the  subsecjuent  di.scovt'ry  of  new 
-pecies  and  al.-io  of  a  new  genus,  together  with  changes  in  nomen- 
clature, have  rendered  a  review  of  the  work  both  nece.<sary  and  de- 
si  ral)le. 

P\dl  descriptions  of  all  the  species  known  to  me  are  given,  and  of 
those  that  have  not  been  identified  descriptions  are  added,  in  most 
ca.<es  in  the  author's  own  words,  thus  aesisting  the  student  to  identify 
his  material  without  the  necessity  of  consulting  scientific  works, 
which  are  often  published  in  foreign  languages,  and  generally  diffi- 
cult <»f  access. 

The  Mutillida?,  unlike  '  e  Formicidfe,  or  social  ants,  are  solitary 
in  their  habits,  and  usuall\  ound  in  hot  sandy  situations.  The  spe- 
cies of  the  genus  Mutilla  ai  now  well  known  to  be  parasitic,  espe- 
cially on  various  species  of  BombuH,  and  it  is  presumable  that  those 
of  the  other  genera  of  the  family  are  likewise  of  the  same  habit. 

The  characters  of  Sphwrophthahna,  which  was  treated  as  a  subgenus 
in  the  "  Synojxsis,"  appear  to  be  sufficiently  constant  and  distinct  to 
warrant  its  elevation  into  a  genus  ;  the  smooth,  round  eyes  sej)arating 
it  at  once  from  Mutil/a,  which  have  the  body  less  coarsely  scul})tured 
and  not  so  densely  hii-sute. 

The  selection  of  the  name  Agama  used  for  a  genus  erected  for  the 
reception  of  those  species  characterized  by  the  i.ore  or  less  shining 
unicolorous  body,  unusually  large  eyes  and  ocelli,  and  hyaline  wings 
was  unfortunate,  a.s  it  was  preoccupied  in  the  Reptilia,  a  fact  over- 
looked at  the  time.  The  name  Photopsis  is  therefore  suiistituted. 
Of  this  genus  the  males  only  are  known,  and  it  is  possible  tiiat  tlic 
females,  which  have  thus  far  escaped  the  observations  of  collectors, 
are  larviform  and  subterraneous  in  their  habits. 

Chi/photej*  is  the  name  I  propose  for  a  new  genus,  characterized 
by  the  binodose  thorax  and  petiolate  abdomen,  the  fii-st  segment  of 
which  is  very  slender  at  base  and  suddenly  dilated  and  nodose  at 
aj)ex  ;  the  eyes  are  smooth  and  round,  as  in  Splmrojihihnhnit ,  while 
the  absence  of  ocelli  ^  parated  it  from  Myrmom

CIIAKLEH    A.    RLAKK. 


I 


The  genus  Apterogtjna,  which  does  not  appear  to  have  been  found 
in  North  America,  is  remarkable  for  the  two  anterior  segments  of 
the  abdomen  being  constricted  and  ^lodose,  and  for  the  great  length 
of  the  antennae  in  the  male,  being  ne  irly  as  long  as  the  body,  and 
for  the  curious  neuration  of  the  wings. 

The  genus  Bradynobiemts,  also  exotic,  is  characterized  by  the  large 
iiuadrate  head,  having  the  anterior  and  posterior  angles  acute,  and 
the  thorax  of  the  female  being  divided  in  two  parts ;  the  femora  and 
tibiae  are  more  robust  than  in  the  other  genera  of  the  family. 

In  Myrmom  the  head  is  subglobose,  eyes  small  and  round ;  the 
thorax  ovate  and  the  anterior  wings  have  one  marginal  and  four 
submarginal  cells.    The  females  of  our  species  appear  to  be  unknown. 

In  the  genus  Methoca  the  ocelli  are  said  to  be  distinct  in  both  sexes, 
head  saliglobose  in  the  female,  transverse  in  the  male,  eyes  ovate, 
thorax  trinodose  in  the  female  and  oblong  in  the  male. 

Nothing  definite  appears  to  be  known  of  their  habits,  although 
they  are  supposed  to  be  parasitic.  Owing  to  the  dissimilarity  of  the 
two  sexes  Latreille  considered  the  male  belonging  to  a  distinct  genus, 
Tengyra,  which  was  arranged  among  the  Scoliidae. 

I  have  divided  the  family  into  nine  genera,  in  all  of  which  the 
females  are  apterous,  and  may  be  tabulated  as  follows : 

Anteniiffi  of  male  flabellate 1,  I'liaininotherina. 

Anteniiffi  simple  in  both  sexes. 

Eyes  ovate,  emarginate  in  the  maie,  entire  in  *he  female 2,  Mutilla.  /''

First  and  second  abdominal  segments  nodose,  anterior  wings  with  two  sub- 
marginal  cells,  marginal  cell  wanting ''''(),  Apterogyiia. 

Mandibles  elongate,  arcuate,  the  maxillary  palpi  3-jointed,  labial  palpi 

2-jointe('. ;  thorax  divided  in  two  parts •■7,  Bradyiiobeenus. 

Eyes  small,  round  ;  head  subglobose,  mandibles  tridentate  in  the  male,  uniden- 
tate  in  the  female ;  wings  with  ;tne  marginal  and  four  .submarginal 
cells;  margins  of  the  abdominal  .segments  crenate,  tridentate  at  apex. 

K,  Myrinosa. 
Eyes  ovate,  ocelli  placed  high  on  the  vertex  ;  antennte  filiform,  mandibles  ar- 
cuate iu  the  female ;  head  subglobose  ;  scape  of  male  anteume  very

Male. — Head  usually  transverse  and  com  pressed,  eyes  moderately 
large,  ovate,  more  or  less  emarginate,  but  in  a  few  species  they  are 
entire.  Ine  ocelli  placed  in  a  triangle  on  the  vertex.  The  anteiniai 
suhfilif'ornk,  gradually  tapering  to  the'  apex,  which  is  acuminate,  in- 
serted on  the  sides  of  the  base  of  the  dypeus.  The  nuuidihles  ar- 
cuate and  tridentate,  but  varying  occasionally  in  this  respect.  The 
prothorax  extending  latersilly  to  the  origin  of  the  wings;  the  teguijc 
usually  very  large.  The  anterior  wings  with  one  marginal  and  three 
subnuirginal  cells,  the  marginal  usually  of  a  semi-circular  form;  the 
three  submarginal  cells  subequal,  the  second  and  third  each  receiving 
a  recurrent  nervure,  tiie  second  nervure  being  almost  obsolete,  as 
well  as  the  third  transvei-so-cubital  nervure,  from  the  middle  of  which 
emanates  a  more  or  less  abbreviated  nervur(>,  never  extending  to  the 
ai)ex  of  the  wing;  in  a  few  exotic  species  the  third  submarginal  cell 
is  obsolete.  The  legs  moderately  long  and  pubescent.  Abdomen 
ovate,  the  first  segment  subpyriform  or  sometimes  })etiolate,  the  second 
campanulate,  and  the  apex  curved. 

F'-inah'. — Head  suborbiculate,  or  sub((uadrate,  sometimes  enor- 
mously developed  and  armed  beneath  with  two  or  more  formidable 
spines  ;  the  ocelli  always  wanting,  the  eyes  ovate,  entire  ;  mandibles 
arcuate  and  usunlly  unidentate.  Thorax  longitudinal  and  truncate 
interiorly  and  posteriorly;  in  some  exotic  species  nuich  narrowed 
behind.  Legs  more  robust  than  in  the  nude  and  armed  exteriorly 
with  spines.     Abdomen  similar  to  the  male. 

The  species,  which  are  not  numerous,  may  be  divided  into  three 
divisions,  viz. :
